Filter Behaviour Inconsistent

Hi there,

I've found previous topics that are similar to this issue, but not quite the same.

On questions, but not on dashboards, dropdown filters for variables will allow for multi-selection of options, selected from a list. This can be restricted, based on permissions of the joined tables that the variable refers to.

For example, if I have a table of schools, and I refer to it in a question via a variable, a dropdown filter can be added which allows for selection of any number of those schools, from a list. If I prevent a user's access to the schools table, they can still use the filter, and view the question, but cannot select options from a list.

The exception comes in when a referred to table is linked to the User table. In that instance, no matter the permissions, for any non admin user, the dropdown list will not appear. I can give identical visibility and permissions to a user who is not an admin, but under no circumstances will that drop down list appear in the filter.

This results in a difference of this:

To this:

The difference in what is observed between an admin user, and a full permissions "Normal" user is the perplexing part. If anyone has observed this, or has any insights, please let me know.

Thanks
